At each of the corners of-the cup member 3 is placed a vertical rod 8, which carries a frame 9. Encirclingthe rods 8 are coil springs 10, upon which the frame-9 rests, the frame 9 being 7 cushioned i thereby. Slidinglyv mountedtuponsthe uprights 8-8 are bars 11, which run diagonally across the frame 9, and thus form a support for the sheet to be printed, represented by 12.

This mechanism. comprises a ratchettwheel' 39 rfast on.;thev1shaftl'.36a.Adjacentthe ratchet; wheel -;39 'are ,mounted two loose.

arms 40 and 41 on the shaft ao. Each one of theseiarms 40 andfill carries a :catch 42 and 4:3. The catch-'42 carries an elongated portion A4- provided with a plurality of holes--45: :drilled therein. Pivotally: secured in one of theholes 45 by means of a pin 47 is-ga 'connectingrod t6, the upper end of which-is pivoted at 48 andcarries a removableand adjustable socket 4:9 regulated by .means of nuts 50. The pivot 48, engages a slotted-bar-5l-carried.by a pivoted lever 52 on the bed framework. The adjustable socket 49 permits the rod 46 to be fastened at any point along the slotted bar 51. The other arm of'the lever 52 carries a bolt 53 which carries an anti'friction roller 54 which is adapted to slide in a slotted bar 55 fixed to the side of the movable carriage 15.

A balance weight 56 is fixed to the hub of the arm 40 on the same side of shaft 36 as the arm 40. Formed integral with the arm 40 and extending at an opposite direction late to a certain extent the speed of the said .movement of the carriage 15.

wheel. A handle 62 is mounted on the shaft 36. I

The operation of this device is a follows: A sheet or plate to be printed, represented at 12, is placed on the frame formed by the bands 11 directly above the stencil plate. Any suitable ink, enamel or pigment is placed in the receptacle 61 formed by the cylinder 2 above the piston head 26. It is necessary to bring the ink level with the top of the stencil 5. r and 43 are disengaged from the wheel 39 and the shaft 36 rotated by means of the handle 62 fixed thereon. This rotation of the shaft 36 rotates the'gear wheel 35 which in turn drives the gear train 33, 34, 31, which rotates the nut 32, which acts upon the threaded bar 27 to raise the piston 26.. to the desired level.

The piston is operated by the bed 15 in the following manner: The carriage -15 being at the back of the machine upon a movement of the carriage to the front it causes the slotted bar 55 to push the bolt 53 down- Ward which causes the lever 52 to have a corresponding upward movement. This u ward movement through the medium of t 1e connecting rod 46 upon the'tail 4401 the catch 42 which is then thrown into engagement with the teeth of the wheel 39 and thus turns the wheel 39 as long as the up- -ward pull upon the rod 46 by the lever 52 continues or during the entire forward This rotation of the wheel 39 causes the shaft 36 to operate the gears 35, 34, 33 and 31 to turn the nut 32 to operate upon the threaded rod 27 to operate the piston 26; The return movement of the carriage 15 will cause the inverse movement of the preceding action b means of a depression of the rod 46 whic causes the catch 42 to disengage. The catch 43 is now engaged with the wheel 39 by means of the balance weight 56, which operates the arm 59 to raise the spring finger 57 which kicks in the catch 43. The catch 43 being positioned away from the teeth of the wheel 39, part of the driving stroke of the weight 56 is taken up in kicking in'the catch 43 with the result that the piston 26 is not withdrawn with as long a stroke as it To do this the catches 42 is raised. By reason of this a few alternate strokes of the carriage 15 will raise the piston head suiliciently to bring the level of the ink or suitable material even'with the top surface of the stencils. The difference in length between the ascending and descending strokes of the piston 26 is regulated proportionately to the quantity of ink consumed at each impression. This is done by regulating the spring finger 57 by raising or lowering it in the rib 58 of the arm 59 until the desired len h of the downward stroke is secured. regulated by means of the adjustable collar 49 of the rod 46 which is operated by means of the nuts 5050. The lower end of the rod 46 may be placed in any one of the holes 45 m the tail 44 of the catch 42, thus regulating the distance the rod 46 travels.

The printing operation is as follows: After the machine has been suitabl regulated the carriage 15 is brought to t e front of the machine, which raises the piston 26, as previously described. This raises the ink level to the height of the stencils. The lever 21 is now operated to lower the platen 13, which presses on the frame 9 against the action of the springs 10. The thick ink passes through the stencil characters and forms raised characters upon the plate to be printed which, when dry, constitutes an impression in relief. To remove the plate 12, the carriage 15 is pushed rearwardly. This movement of the carriage 15 causes the piston 26 to descend. As the descent of the piston is made b a stroke somewhat shorter than the upwar stroke when the'piston reascends the lengthening of the up-stroke will compensate for the quantity of the-ink used in the previous impression. This action follows until the ink holder is completely empty.

The machine being described is adapted more particularly for hand operation, but it is clearly evident that the drive for the machine could be mechanical.

Considerable variation of the details of this invention may be resorted to without variation from the spirit thereof.
